Crushing Coils (Ex) A creature that takes damage from a marilith's constrict attack must succeed on a DC 25 Fortitude save or lose consciousness for 1d8 rounds. The save DC is Strength-based.
Infuse Weapon (Su) Any weapon a marilith wields gains a +1 enhancement bonus to attack and damage, and strikes as if it were a chaotic and evil cold iron weapon (in addition to retaining the qualities of its actual composition).
Multiweapon Mastery (Ex) A marilith never takes penalties to her attack roll when fighting with multiple weapons.
The leaders of Abyssal hordes and queens of Abyssal nations, the dreaded mariliths serve demon lords as governesses, advisors, and even lovers, yet their brilliance as tacticians makes them most sought after as generals and commanders of armies. The most powerful mariliths serve no one, and instead command ravenous fiendish legions.
A marilith is 6 to 9 feet tall and measures 20 feet from head to tail tip. It weighs 4,000 pounds. Only the most arrogant and proud evil souls, typically those of cruel kings, sadistic generals, and exceptionally violent warlords, can trigger the manifestation of a marilith.
